ORE CAR.

SPECIFICATION forming part of Letters Patent No. 695,344, dated March 11, 1902.

Application filed March 25,1901. Serial No. 52,841. (No model.)

erence being had to theaecompanying draw-' ings, and to the figures of reference marked thereon,which form a partof this specification.

My invention relates to improvements in ore-cars, my object being to make it practicable to have the load centrally located and bear equally on the two pairs of wheels of a dumping-car. As heretofore constructed the dumping extremity of these cars projects beyond the wheels farther than the rear extrem ity in order that the car may be ready to.

dump as soon as its rear extremity is released. This arrangement results in throwing the greater portion of the load on one pair of wheels, which. are thereby unequally Worn. There is also a tendency on the part of the car to tip over bodily upon striking an obstacle on the track. Hence myobject is to overcome these difficulties and to this end the invention consists of a car whose body portion is manually movable endwise on the revoluble platform of the truck, sothat while normally the load is equally balanced on the truck the ear-body may be shifted when the car has reached the dumping point or station.

Having thus briefly outlined my improvement and stated the objects to be accomplished thereby, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side elevation of my improved oar shown in its normal position-that is to say, balanced on the platform or truck. Fig. 2 is a similar view showing the car in the dumping position. Fig. 3 isa section taken on the line :0 as, Fig. 4. Fig. at is a section taken on the line A A, Fig. 1. Fig. 5 is a section taken on the line/y 3 Fig. 4. Fig. 6 is a section taken on the line a 2, Fig. 5.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the car-body, and 6 the platform, revolubly mounted on the truck 7. The car-body is connected with the platform 6 by means of a shaft 8, journaled in bearings 9, fast on the platform. This shaft is also journaled in the forward extremities of track-rails 10. The upper portion of each of these rails is T-shaped in cross-section and engages a groove of counterpart shape formed in a bar 12, fast on the bottom of the car, whereby the car-bod y is slidable endwise on the platform and atthe same time mounted to turn on the shaft 8 as an axis to assume the dumping position. It will be observed that when the car-body dumps (see Fig. 2) the track-rails 1O tip therewith by virtue of the connection between the T-shaped rails and the bars 12.

Fast on the shaft 8, outside of each rail 10, is a gear or pinion 13, which engages acogged rack 14, fast on the bottom of the car-body outside of the bar 12. The shaft 8 protrudes beyond the body of the car on one side, and to this protruding extremity is made fast a toothed wheel 15. A hand-lever 16 is pivoted on the shaft adjacent the toothed wheel. On thislever is pivotally mounted a dog 17, one extremity of whichis connected with a springactuated rod 18, connected with a handpiece 19, pivoted on the body of the lever, the arrangement being such that the dog 17 is normally held disengaged from the toothed wheel. When the handpiece 19 is grasped by the hand of the user,the dog will be thrown into engagement with the wheel, whereby the shaft may be turned in either direction, as desired.

The body of the car is connected at the rear with the truck-platform by means of .a depending hinged plate or latch 20, arranged to engage a projection 21. This latch 20 is connected, by means of a link 22, with a lever 23, fulcrumed on the rear extremity of the carbody, as shown at 24. The latch may be disengaged from the platform by means of this lever. This construction also prevents the car from sliding forward accidentally on the track-rails, as otherwise might be the case on inclines.

The hinged door 5 of the car-body is normally locked by a dog 25, pivoted on a'T shaped block 26, slidable in a counterpart way 27, formed on the bottom of the car. One arm of the dog is connected, by means of a rod 28, with the shaft 8, which is journaled in the rear extremity of the rod, as shown at 28. When the car-body is in its normal position, as shown in Figs. 1, 3, and 5, the dog 25 is held in a position to lock the door 5 close-d. When, however, the carbody is moved to the dumping position, (see Fig. 2,) the dog is made through the instrumentality of the rod to assume the position shown in Fig. 2, allowing the car-door to swing outwardly.

From the foregoing description the use of my improved ore-car will be readily understood. WVhen it is desired to dump the car, the lever 16 is actuated to turn the shaft, whereby, the pinions 13, through the instrumentality of the racks 14, cause the car-body to move forward to the dumping position. Before moving the car-body to this position the latch 20 is disengaged from the projection 21. After the car-body has dumped its load and is tipped to the horizontal position it may be returned to its normal or balanced position by turning the shaft 8 in the reverse direction from its movement when moving the car-body forward.

Having thus described my invention, what I claim is- 1. In a car the combination with a truck, of a track pivotally mounted thereon, and a car-body slidable on the track.

2. In a car the combination with a truck, of a track hinged or pivoted thereon and a car-bodyslidable on the track and operatively' connected therewith.

3. The combination with the car-truck and platform, of a track pivoted on the platform, and a car-body slidable on the track and mounted to move back and forth thereon for the purpose described.

4. The combination with a car-truck, of a track hinged or pivoted thereon and a carbody connected with the track and arranged to move back and forth in a direction at right angles to the axis of its pivot.

5. The combination with a car-truck of a shaft jonrnaled in suitable bearings on the truck, track-rails pivoted on the shaft, and a car-body movable on the rails.

6. In a car the combination with a truck, of track-rails pivoted on the truck, the carbody movable on the rails in a direction at right angles to the pivot, and suitable means for shifting the car-body on the pivoted trackrails.

11. The combination with a truck, and a car-body, of a track hinged or pivoted on the truck, the car -body being slidable on the track and provided with a hinged door, means for locking said door in a closed position, and a connection between the car-truck and said locking means whereby the latter is controlled as the car-body is shifted.
